My wife and I just went on a adult vacation lol Went to swinger clubs and adult stores from Arkansas to Florida. I saw a few things that looked like it would work very well.
In the swing clubs and adult stores they had 5 x 7 very nicely printed cards advertising there websites. Pretty big selection of them 2...At the first of the night at the club, they started with a big stack of all of them...at the end of the night everything on the rack was gone...cost $125 bucks just to get in the door...so most the people had money...should convert well.
Also got a kick ass magazine...The new Florida Playtime...all ads for escorts and adult clubs...
http://www.playtimemagazine.com I havent looked at the site yet but the magazine is great.
